2014-07-25scsi: convert target_busy to an atomic_tChristoph Hellwig1-2/+2
Avoid taking the host-wide host_lock to check the per-target queue limit. Instead we do an atomic_inc_return early on to grab our slot in the queue, and if necessary decrement it after finishing all checks.

2014-07-17scsi: restructure command initialization for TYPE_FS requestsChristoph Hellwig1-1/+0
We should call the device handler prep_fn for all TYPE_FS requests, not just simple read/write calls that are handled by the disk driver. Restructure the common I/O code to call the prep_fn handler and zero out the CDB, and just leave the call to scsi_init_io to the ULDs.

2014-07-17scsi_scan: Restrict sequential scan to 256 LUNsHannes Reinecke1-0/+2
Sequential scan for more than 256 LUNs is very fragile as LUNs might not be numbered sequentially after that point. SAM revisions later than SCSI-3 impose a structure on LUNs larger than 256, making LUN numbers between 256 and 16384 illegal. SCSI-3, however allows for plain 64-bit numbers with no internal structure. So restrict sequential LUN scan to 256 LUNs and add a new blacklist flag 'BLIST_SCSI3LUN' to scan up to max_lun devices.

2014-07-17sg: add SG_FLAG_Q_AT_TAIL flagDouglas Gilbert1-0/+1
When the SG_IO ioctl was copied into the block layer and later into the bsg driver, subtle differences emerged. One difference is the way injected commands are queued through the block layer (i.e. this is not SCSI device queueing nor SATA NCQ). Summarizing: - SG_IO in the block layer: blk_exec*(at_head=false) - sg SG_IO: at_head=true - bsg SG_IO: at_head=true Some time ago Boaz Harrosh introduced a sg v4 flag called BSG_FLAG_Q_AT_TAIL to override the bsg driver default. This patch does the equivalent for the sg driver. ChangeLog: Introduce SG_FLAG_Q_AT_TAIL flag to cause commands to be injected into the block layer with at_head=false.

2014-07-17scsi: increase upper limit for max_sectorsAkinobu Mita1-2/+2
max_sectors in struct Scsi_Host specifies maximum number of sectors allowed in a single SCSI command. The data type of max_sectors is unsigned short, so the maximum transfer length per SCSI command is limited to less than 256MB in 4096-bytes sector size. (0xffff * 4096) This commit increases the SCSI mid level's limitation for max_sectors upto the block layer's limitation for max_hw_sectors by extending the data type of max_sectors in struct Scsi_Host and scsi_host_template, so that SCSI lower level drivers can specify more than 0xffff.

2014-07-14neigh: sysctl - simplify address calculation of gc_* variablesMathias Krause1-1/+0
The code in neigh_sysctl_register() relies on a specific layout of struct neigh_table, namely that the 'gc_*' variables are directly following the 'parms' member in a specific order. The code, though, expresses this in the most ugly way. Get rid of the ugly casts and use the 'tbl' pointer to get a handle to the table. This way we can refer to the 'gc_*' variables directly.

2014-07-03ptrace,x86: force IRET path after a ptrace_stop()Tejun Heo1-0/+3
The 'sysret' fastpath does not correctly restore even all regular registers, much less any segment registers or reflags values. That is very much part of why it's faster than 'iret'. Normally that isn't a problem, because the normal ptrace() interface catches the process using the signal handler infrastructure, which always returns with an iret. However, some paths can get caught using ptrace_event() instead of the signal path, and for those we need to make sure that we aren't going to return to user space using 'sysret'. Otherwise the modifications that may have been done to the register set by the tracer wouldn't necessarily take effect. Fix it by forcing IRET path by setting TIF_NOTIFY_RESUME from arch_ptrace_stop_needed() which is invoked from ptrace_stop().

2014-07-03[SCSI] use the scsi data buffer length to extract transfer sizeMartin K. Petersen1-1/+1
Commit 8846bab180fa introduced a helper that can be used to query the wire transfer size for a SCSI command taking protection information into account. However, some commands do not have a 1:1 mapping between the block range they work on and the payload size (discard, write same). After the scatterlist has been set up these requests use __data_len to store the number of bytes to report completion on. This means that callers of scsi_transfer_length() would get the wrong byte count for these types of requests. To overcome this we make scsi_transfer_length() use the scatterlist length in the scsi_data_buffer as basis for the wire transfer calculation instead of __data_len.

2014-07-02kernfs: kernfs_notify() must be useable from non-sleepable contextsTejun Heo1-0/+1
d911d9874801 ("kernfs: make kernfs_notify() trigger inotify events too") added fsnotify triggering to kernfs_notify() which requires a sleepable context. There are already existing users of kernfs_notify() which invoke it from an atomic context and in general it's silly to require a sleepable context for triggering a notification. The following is an invalid context bug triggerd by md invoking sysfs_notify() from IO completion path.

2014-07-01core: fix typo in percpu read_mostly sectionZhengyu He2-3/+3
This fixes a typo that named the read_mostly section of percpu as readmostly. It works fine with SMP because the linker script specifies .data..percpu..readmostly. However, UP kernel builds don't have percpu sections defined and the non-percpu version of the section is called data..read_mostly, so .data..readmostly will float around and may break things unexpectedly. Looking at the original change that introduced data..percpu..readmostly (commit c957ef2c59e952803766ddc22e89981ab534606f), it looks like this was the original intention. Tested: Built UP kernel and confirmed the sections got merged. - Before the patch: $ objdump -h vmlinux.o | grep '\.data\.\.read.*mostly' 38 .data..read_mostly 00004418 0000000000000000 0000000000000000 00431ac0 2**6 50 .data..readmostly 00000014 0000000000000000 0000000000000000 00444000 2**3 - After the patch: $ objdump -h vmlinux.o | grep '\.data\.\.read.*mostly' 38 .data..read_mostly 00004438 0000000000000000 0000000000000000 00431ac0 2**6 Signed-off-by: Zhengyu He <hzy@google.com> Signed-off-by: Filipe Brandenburger <filbranden@google.com> Signed-off-by: Tejun Heo <tj@kernel.org>
2014-06-30ipv4: irq safe sk_dst_[re]set() and ipv4_sk_update_pmtu() fixEric Dumazet1-6/+6
We have two different ways to handle changes to sk->sk_dst First way (used by TCP) assumes socket lock is owned by caller, and use no extra lock : __sk_dst_set() & __sk_dst_reset() Another way (used by UDP) uses sk_dst_lock because socket lock is not always taken. Note that sk_dst_lock is not softirq safe. These ways are not inter changeable for a given socket type. ipv4_sk_update_pmtu(), added in linux-3.8, added a race, as it used the socket lock as synchronization, but users might be UDP sockets. Instead of converting sk_dst_lock to a softirq safe version, use xchg() as we did for sk_rx_dst in commit e47eb5dfb296b ("udp: ipv4: do not use sk_dst_lock from softirq context") In a follow up patch, we probably can remove sk_dst_lock, as it is only used in IPv6.

The "aclk66_peric" clock is a gate clock with a whole bunch of gates underneath it. This big gate isn't very useful to include in our clock tree. If any of the children need to be turned on then the big gate will need to be on anyway. ...and there are plenty of other "big gates" that aren't described in our clock tree, some of which shut off collections of clocks that have no relationship in the hierarchy so are hard to model. "aclk66_peric" is causing earlyprintk problems since it gets disabled as part of the boot process, so let's just remove it. Strangely (and for no good reason) this clock is exported as part of the common clock bindings. Remove it since there are no in-kernel device trees using it and no reason anyone out of tree should refer to it either.
